So no personal experience at 7-08 speeds... check.
I've killed many truck loads of animals with a 7x57, some of them pretty big. I have mostly shot 140 TTSX Barnes at about 2900 fps whitetails, kudu, gemsbuck whatever. It will penetrate at pretty much any angle, which the Sierra won't. I've shot a ton of Sierras in the old days, when there weren't premium bullets, broadside shots through both lungs, they are deadly, bad angles, no thanks.
